[texts]5. Maths IJMCAR A RESULT ON THE MEASURE Kenchappa S Betageri
We study a survey paper about pseudo-random graphs by Krivelevitch and Sudakov [1], there they have considered ( )-graphs and we too. In this paper present some of the theorems and lemmas from it and we answer fortheir question how small can be second adjacency eigenvalue of graph that measure the pseudo randomness of graphs. We extended it to the second normalized Laplacian eigenvalue to measure the pseudo randomness of graph.

[texts]11. Maths IJMCAR On The Connectivity Of KENCHAPPA S BETAGERI
In this paper we discuss some theorems about pseudorandom graphs by Krivelevitch and Sudakov [1] and generalized them on the basis of edge-connectivity, vertex-connectivity of graph G through an eigenvalue. Here, we give a solution for the question raised in [1], for what are the possible values of second Laplacian eigenvalue of graphs on n vertices with an cut-vertex?

[texts]Non-intrusive measurements in a rocket engine combustor - Farhangi, S.
In recent years analytical tools to characterize combustor flow have been developed in order to support design. To facilitate anchoring of combustion related physical models and the CFD codes in which they are incorporated, considerable development and application of non-intrusive combustion diagnostic capabilities has occurred. Raman spectroscopy can be used to simultaneously detect all polyatomic molecules present in significant concentrations and to determine gas temperature...

[texts]Low Angle Silicon Sheet Growth. Large Area Silicon Sheet Task Low Cost Solar Array Project - NON
The results of a program to demonstrate the feasibility of a low angle silicon ribbon growth process are described. Twenty-six experimental runs were performed. Ribbons were grown at pull rates from 5 to 68 cm/min. Ribbon lengths up to 74 cm were grown while widths varied from 5 to 25 mm. Thicknesses varied from 0.6 to 2.5 mm, with typical values of about 1 mm.

[texts]Response to ''No Evidence for Iris'' - Chou, Ming-Dah
Hartmann and Michelsen claimed that there was no evidence for the negative relation between the high-level clouds and the sea surface temperature as suggested by Lindzen et al. The assertion made by Hartmann and Michelsen that there is a need for clouds thousands of kilometers away from the equator to be connected to convection at the equator does not seem to have any validity. Nor does their suggestion that the causes of the observational relations shown in Lindzen et al...

[texts]Solution of One-dimensional Hyperbolic Problems Using Cubic B-Splines Collocation
In this paper we extend the cubic B-splines collocation method to enable it to solve one-dimensional hyperbolic (eigenvalue and wave propagation) problems under arbitrary boundary conditions. This is achieved by analogy with the finite element method, introducing a ‘collocation mass matrix’ that cooperates with the previously known system matrix, now called ‘collocation stiffness matrix’. In agreement with earlier findings on elliptic problems, we found that in time-dependent problems it...

Ho:Tm:Er:LuAG demonstrated simultaneous laser oscillation associated with two different transitions and different atoms. Two wavelength oscillation, or TWO, can be achieved in a single laser and single resonator. Moreover, the wavelength can be electronically controlled by varying the pump pulse length, Either the short wavelength, the Ho (5)1(sub 7) to (5)1(sub 8) transition at 2.1 microns, or the long wavelength, the Er (4)1(sub 11/2) to (4)1(sub 13/2) transition at 2.7 microns, or both wavele...

[texts]High Voltage TAL Performance - Jacobson, David T.
The performance of a two-stage, anode layer Hall thruster was evaluated. Experiments were conducted in single and two-stage configurations. In single-stage configuration, the thruster was operated with discharge voltages ranging from 300 to 1700 V. Discharge specific impulses ranged from 1630 to 4140 sec. Thruster investigations were conducted with input power ranging from 1 to 8.7 kW, corresponding to power throttling of nearly 9: 1...

An analysis based on plate finite elements and the virtual crack closure technique has been implemented to study the effect of stitching on mode I and mode II strain energy release rates for debond configurations. The stitches were modeled as discrete nonlinear fastener elements with a compliance determined by experiment. The axial and shear behavior of the stitches was considered, however, the two compliances and failure loads were assumed to be independent...

[texts]Eigenmode Analysis of the Thermoacoustic Combustion Instabilities Using a Hybrid Technique Based on the Finite Element Method and the Transfer Matrix Method
Thermoacoustic combustion instabilities affect modern gas turbines equipped with lean premixed dry low emission combustion systems. In the case of annular combustion chambers, experimental test cases carried out on small scale test rigs equipped with single burner arrangements fail to give adequate indications for the design of the full scale combustion chamber, since they are unable to reproduce the interaction of the flame fluctuation with the azimuthal pressure waves...
